The biggest factor in making ME not linearly proportional to barrel length...

Response to As you say, only the barrel length info:

...is the fact that pressure usually drops rapidly as the charge expands behind the pellet.

So the energy contributed by the last inch of bore is generally much less than the energy contributed by the first inch, simply because the pressure - and therefore the push - behind the pellet is higher near the breech than near the muzzle.
